Overview
The FOD2741ASV is a single-channel optocoupler manufactured by onsemi, featuring a DC input and NPN phototransistor output. It provides an isolation voltage of 5000 Vrms and operates within a temperature range of -40°C to +85°C. The device utilizes an SMD-DIP-8 package for surface mount installation. Key electrical parameters include a forward voltage of 1.5 V, a current transfer ratio of 100%, and a maximum collector current of 50 mA. It supports a maximum collector-emitter voltage of 30 V with a saturation voltage of 400 mV.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical transmission.
- Integrates a DC input LED with an NPN phototransistor output stage for signal amplification.
- Designed for surface mount technology applications requiring compact footprint solutions.
Applications
- Error amplifier circuits in power supply systems
- General purpose optocoupler applications requiring galvanic isolation
- Industrial control systems needing signal transmission across isolated domains
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check production lifecycle status as the part may be subject to obsolescence notices. Ensure packaging specifications match bulk requirements. Validate datasheet revisions against specific manufacturing lot codes for accuracy.
Selection Notes
Select this component when high isolation voltage and surface mount compatibility are required. Consider the NPN output configuration for appropriate load driving capabilities. Evaluate thermal performance within the specified operating temperature range. Verify pinout compatibility with existing PCB layouts designed for SMD-DIP-8 packages. Assess current transfer ratio requirements for signal integrity in the target application.
Part Context
This component belongs to the FOD2741A series of optically isolated amplifiers. It represents a specialized variant within onsemi's optocoupler portfolio, focusing on surface mount implementations. The series typically includes variations distinguished by suffixes indicating packaging or testing configurations. It serves as a bridge between low-power control signals and higher-power isolated sections.
Replacement Considerations
FOD2741ASDV is a documented substitute offering identical functional characteristics with tape-and-reel packaging options. Verify mechanical dimensions and pin assignments before substitution. Ensure electrical parameters remain within acceptable tolerances for the specific circuit design.
